TWISTER RING.-

Application filcd Dccembcr 28,1922; Serial No. 609,490,

To all whom it may concern:

designed more particularly where a series of rings are employed for a single twister irame. v

In the application above mentioned each ring is supported by three bearing rollers. Accordin to the present invention certain bearingrollers are designed to cooperate with eachof a pair of twister rings, so that while each iin'g issuppo'rted by three rollers, the total number of rollers is only two more than twice the number of rings, one of the extra two rollers being required for each end ring of the series.

Further features of' the invention relate to tension devices by which the rotation of the ringsmay be retarded to regulate the tension on the "strands, tom'eans for cleaning andoiling the rings, and to the means for taking up wear, a. more complete understanding of this invention, together with further objects and advantageous details and combinations of parts, reference may be made to the accompanying drawings in which Figure 1 is a fragmentary plan of a rail showing a plurality of twister rings carried thereby.

Figure 2 is a front elevation of the same,

lfli-gure' 3 is a section on line- 3-3 of Figure 1:.

Figure portion of Figured, but showing tion Y neferring' first to Figures 1', 2, and 3, at i indicated a rail for supporting a plural-i-y of twister rings2 arranged'in series and. rotatable in common plane; 'Each ring'is supported above an opening; 3 in the rail and spaced about the margin of this opening are three-bosses, two being indicated at 4;. and one" of larger size at 5. The rail is perforated" centrally iof bosses to receive oil 'cups, .as'shawn att and. 7, find f is a detail section similar to a modificasupported by therail are brackets 8 9, and 10 for carrylng shafts 11 depending within the 011 cups, J ournaled on these shafts are bearing rollers 12 and 13, the rollers 12, which are ca'rriedby the'brackets 8, being larger diameter than the rollers 13 car-' ried by the brackets 9 and 10, These rollers are spaced about the peripheries of the rings 2 substantially equally, and the rollers 12 are formed to engage-the peripheries of a pair of adjacent rings 2, while each roller 13 engages one ring only. 'Each roller has a depending sleeve portion 15' surrounding its respective shaft 11 and which extend beneath the surface of lubricant contained in the cups 6 and 7 by which means these rollers are lubricated on their shafts in substantially the same manner as disclosed in the application above mentioned. Each roller 1-2 and '13 is also'provided with a peripheral groove having marginal flanges 16 which'engage the top and bottom faces ofthe rings so that the'rings are entirely supported thereby.

For the purpose of taking up wear between the various rings and rollers, the rollers 12 may bemade adjustable with respect to the rings. For this purpose the shaft 11 carried by each bracket 8 passes through an enlarged opening 20 therein and may be clamped in position relative to this opening by means of a nut 21 threaded on the upper end of the shaft and bearing against a washer 22 resting on the top of the bracket 8, a collar- 23 being provided on the shaft beneath the bracket 8"between which and the washer 22 the bracket may be clamped;

For the purpose of applying a drag to the rotation of the rings, as well as to clean the rings and topermit lubricant to be applied thereto, braking elements of fibrous material may b s-employed; i-is shown these merits or shoes are indicated at 25 and comprise piecesof; felt of substantially I cross section whichengage the outer faces of the rings 2 and which areheld in; contact therewith by mean-s of'brake heads 26 which are mounted in pairs on resilient arms 27, one shoe being carried by each end of each arm and each arm being. supported. intermediate its ends'on the reduced extremity 28 of a screw pin 29" threaded through alternate brackets 8* and having at its outer end a screw driver slot 3Q by which it may be turned. The reduced-portion 28 of each pin passes through a perforation 31 of the arm 27 which arm may rest against a shoulder 32 formed by a portion of larger diameter than the reduced extremity 28 as at 33. Surrounding this portion 33 and reacting between one face of the arm 27 and the head 34 of the screw is a coil spring 35. By adjustment of the screw the spring 35 may be moved inwardly against the rear face of the arm 2'? until this arm contacts with the shoulder 32, whereupon further movement inwardly of the screw causes pressure to be exerted against the heads 26 to press the braking elements or shoes 25 into contact with the rings by the flexing of the arm 27. By this means the pressure of the braking elements against the ring peripheries may be adjusted as desired in accordance with the character of the yarn being twisted. The felt pad 25 not only exerts a retarding effect on the rotation of the rings, but also acts to clean the rings from foreign matter such dirt or lint which may collect thereon in the operation of the machine. It also furnishes a means by which the bearing faces of the rings may be. lubricated, it being found in practice that when no lubrication is employed the frictional resistance to the rotation of the rings changes with changes of humidity. By lubricating the rings, however, the efl'ect of humidity is eliminated. For this purpose, therefore, each head 26 may be perforated as shown at 40 and through this perforation oil may be applied to the felt 25. While if desired oil may be applied to all the felts for the entire series of rings. if it is applied to one only it is transferred to all the rings of the series, since it is transferred from the nearest ring 2 through its bearing roller 12 to the next adjacent ring and from this ring through the other roller 12 hearing thereon to a succeeding ring and so on through the entire series.

In case it is desired to remove any of the rings this may be readily accomplished by removing the bracket 8 which carries the braking element operating thereon. To remove all the rings it is only necessary to remove every alternate roller 12 by removin: those brackets 8 to which the spring ai-n s 2? are fixed, The other rollers 12 need not be disturbed, as it will be noted'that their brackets carry no braking elements since two of such elements are carried by the same roller bracket,

Each ring provided with a suitable yarn eye, as indicated at L5, the eye shown being that described and claimed in the application above mentioned. As this is positioned entirely within the ring, lubricant from the shoes 25 is not liable to reach the yarn, especially since the centrifugal force due to the rotation of the rings tends to retain the oil on its outer periphery. If desired, however, a construction shown in Figure 4 may be employed in which the ring 200 is made T shape in cross section, the stem of the T forming an outwardly extending annular flange 201 which fits between the roller flanges 16 midway of the top and bottom or end faces of the ring. These parts are so proportioned that the flanges 16 lie substantially flush with the top and bottom faces of the ring and centrifugal force tends to maintain the oil on the flange 201 and prevents it from passing over to the inside of the ring.

From the above description it will be seen that a plurality of rings may be properly supported for rotation with the number of rollers only two greater than the number of rings each ring having a three point support, the rings rotating in a common plane; and also that the same elements not only serve as brakes to retard the rotation of the rings, but also as cleaning elements and lubricant appliers and that it is only neces sary to apply lubricant to one of these elements to insure proper lubrication to the whole series.

Having thus described certain embodiments of this invention it should be evident to those skilled in the art that many changes and modifications might be made therein without departing from its spirit or scope as defined by the appended claims.
